Contributing back to GHC

The following pages describe the process of making a change to GHC and contributing it back. For small changes you can just darcs send, but for larger changes it helps a great deal if the patch is in a form that we can review quickly and use without too much extra work.

Note that, largely due to performance issues in darcs, we currently avoid applying patches with conflicts to the GHC repositories. If you find that you have a conflict in a patch that you want to send or apply, please first unrecord and re-record (or amend-record) it so that the conflict is removed.
